Coventry has the highest pay gap between men and women in the West Midlands, a new survey shows.

Men earn more than £150 a week more than women in the city, according to a report by Britain's General Union, GMB.

Warwickshire has the second highest gender pay gap in the region, at £136 a week.

The GMB is calling on the government to compel employers to undertake equal pay audits to end pay secrecy.

Coventry's gender pay gap is £152 a week - £23 higher than the UK's average of £129 - while the figure for the West Midlands is £113.

The West Midlands Employment and Low Pay Unit has criticised the findings and is advising employers to carry out equal pay audits which can be used to resolve any inequalities without the need for lengthy and expensive litigation.

A WMELPU spokeswoman said: "It's not very satisfactory. £150 is roughly a week's pay on the minimum wage.

"There are reasons for pay gaps arising but they should not be based on gender."
